Major electrical problems

[Daily-Driver]

Where to begin - lol - so I have a MK5 fiesta and recently bought a full leather interior from a mk6 or mk6.5 ghia the front door cards were electric windows so I decided to follow dangerford’s guide (top guide by the way) but installed the mk6 / mk6.5 door wiring looms which obviously don’t match the MK5 wiring loom connectors. Therefore I decided to buy a mk6 wiring loom and install it. I have done this and now the windows work but there seems to be a permenant live somewhere as when I connect the GEM up the side lights come on even though there’s no key in the ignition his includes the rear side lights and the passenger wide indicator stuck on at the rear only! I tried to start the car (before I reconnected the fuel pump wiring and fuel tank connections duh) and it turned over but now I’ve got nothing! It’s a mess can anyone help or advise?

primarily can you use a mk6 wiring loom with a MK5 system?

 

cheers

i can't help with the electrics.  If your car is 2004 then it is known as a Mk6 in the UK (but known as Mk V  or fifth generation in some places).

This is from wikpedia

"Fifth generation (2002–2008) (UK Mk6)[edit]

On April 1, 2002, the all new fifth generation car was unveiled. Production at Almussafes Plant started on April 29, 2002. Of this Fiesta Mark V, most engines were carried over from the previous Fiesta, but renamed "Duratec", as the "Zetec" name was now solely used for sportier models. The previous push-rod 1.3 L engine was initially available in the UK, but this was quickly replaced with a Rocam 1.3 L, both under the name Duratec 8v.^[11] Trim levels available initially were Finesse, LX, Zetec and Ghia, with limited edition variants soon following. The fifth generation was also the first Fiesta to feature the Anti-lock Braking System and passenger airbags as standard. The fifth generation was occasionally referred to as Mark VI in United Kingdom and elsewhere due to the fourth generation facelift being commonly referred to as the Mark V. This generation became the best-selling Ford Fiesta generation to date."

 

although it says "The fifth generation was occasionally referred to as Mark VI in United Kingdom " , it is much more than occasionally - I would say usually.
